LASTINGr-MAGHINE.

Application filed November 22, 1916.

To all whom it may concern: I

. Be it known that I, MA'r'ri-ims BROOK, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines and is herein shown as applied to a machine of the type shown in prior United States Letters Patent No. 1,066,375, granted July 1, 1913, upon my application.

In the use of a machine of the type shown, a shoe is applied to a heel spindle while the spindle occupies a depressed and advanced position with relation to a heel band and heel seat wipers relatively to which it is subsequently jacked backwardly and upwardly into operative position by mechanism which includes a hand wheel for drawing the shoe back and a foot treadle for raising the shoe. In the machine shown in said patent the foot treadle and hand wheel are locked by separate pawls to maintain the jacking pressures at the heel. The machineis also equipped with toe jacking mechanism, including a foot operated treadle one depression of which effects jacking up of the toe of the shoe and the next alternate depression of which efiectsthe unjacking of the toe. In accordance with a time and labor saving feature of the invention covered by that patent, the unjacking of the heel is caused to follow automatically the unjacking of the toe. It is an object of this invention to improve the machine of United States Letters Patent No. 1,066,375 in respect to this feature. In the machine the pawl that locks the foot treadle controlling the heel pressure was operatively connected with the toe jacking foot treadle, as shown in Fig. 13 of the patent drawings, so that the pawl was lifted by every depression of the toe jacking tread'le. Therefore the operator could not jack up the heel until after he had jacked up the toe, because the toe jacking would release the heel jacking treadle. The shoe must, however, be jacked back into the heel band before the toe j ack- Specification of Letters Patent.

ing is effected, as is well understood. I have found that there is a substantial advantage in jacking the heel up to approximately its full elevation relatively to the wipers before it is jacked back into the hand, because if the jacking up follows the jacking back it tends to force the last up too much within the shoe upper materials, disarranging the latter. In prior United States Letters Patent, No. 1,018, 177 granted February 27, 1912, upon my application, a treadle is provided for raising the heel post which is inde pendent of the toe post elevating mechanism, the machine, however, not being provided with mechanism for automatically lowering the heel post concurrently with the lowering of the toe post as in prior United States Letters Patent No. 1,066,375. It is an object of my invention to provide a lasting mechanism which will have the advantage of the labor-saving feature of prior United States Letters Patent No. 1,066,375 with the additional advantage of a construe tion permitting operation in the desired setion of a lasting machine equipped with the present improvements.

Fig. 2 shows in end elevation a portion of the means with which machines of the illustrative type are provided for raising and lowering the toe post.

Fi g. 3 shows in front elevation and partly in vertical section a portion of the mechanism of Fig. 2 together with the means with which machines of this type are provided for releasing the heel lasting carriage.

Fig. 4 is a perspective view illustrating novel portions of the mechanism of this invention.

The machine which in general resembles closely the machine fully described in prior Patent No. 1,066,375,. comprises a frame At upon the right hand end of which a heel lasting mechanism B, including a movable heel lasting carriage, occupies a constant operative position in which it is held by a latch 144 and from which it is moved rearwardly to permit insertion and removal of the work. The heel lasting mechanism comprises a heel band 2 and heel seat wipers 3. The frame A also supports a toe lasting mechanism C which is adjustable thereon toward and from the heel lasting mechanism to adapt the machine for operating upon shoes of different lengths. The shoe is supported for the lasting operation by a heel post carrying a last spindle 5, and by a toe post carrying a toe rest 6 and which-is arranged to be elevated by the mechanism disclosed in said prior United States Letters Patent No. 1,066,375 and controlled by foot treadle 17 6 for jacking up the toe of the shoe, and to be returned to lowered position in response to a second actuation of treadle 17 6 for unj acking the shoe to permit it to be removed from the machine. This mechanism as shown in Figs. 2 and 3 comprises a cam shaft 9 to which is fixed a ratchet wheel 10 engaged by a pawl 11 mounted on a pawl carrier 12 which is supported loosely for turning movement on the cam shaft 9 and connected by a rod 13 with the treadle 17 6. The shaft 9 carries a cam wheel 14 having alternate elevations and depressions and arranged to engage a roll 17 on a vertically movable slide 18 which is guided in the frame of the machine and is constructed to provide a support for the toe post by engagement with an adjustable screw 19 at the lower end of the post. In the operation of this mechanism one depression of the treadle 176 will serve to turn the ratchet wheel 10 a sufficient distance to move one of the elevations of the cam wheel 14 beneath'the roll 17 and thereby elevate the toe post, which will remain in elevated position until the next succeeding depression of the treadle 176 whereby the cam shaft will be turned a sufiicient distance to remove the elevated portion of the cam wheel from beneath the roll 17 and permit the toe post to return to its lowered position.

The heel post is vertically movable in a horizontally movable slide 8 which has operative connection with a hand wheel 148 by means of which the heel post is jacked back into the heel band after a shoe has been applied to the last spindle. The extent to which the heel post, with the shoe thereon, can be acked back into the band depends upon the size of the shoe or the last and the position of the spindle hole in the last with relation to the rear end face of the last. There is therefore provided, as fully 6X- plained in said Patent 1,066,375, a friction pawl 150 for locking the hand wheel, together with mechanism fully described in said patent, for automatically unlocking the hand wheel when the shoe is to be unjacked.

The heel spindle rests down, by an adjustable screw bolt 15, as shown in Fig. 4,'upon the vertically swinging plate 16 the rear end of which is pivoted to the slide 8 and the front end of which in turn rests upon an elevating rod 210 operatively connected at its lower end witha foot treadle 212 having a ratchet face adapted to be engaged by a locking pawl 214 pivoted at 215 andhaving a foot piece 218 by which the pawl can be lifted independently of the movement of any other part of the machine. Under normal conditions, however, it is desirable to save an operator the time and effort of manipulating the pawl 214 to unlock the ele-- vating rod. In accordance with this invention this result is obtained by mechanism that is unaffected by that depression of the toe rest treadle 17 6 which is employed for jacking up the toe of the shoe, as will be hereinafter explained. This organization makes it possible for the operator, after having applied a shoe to the heel spindle 5, to elevate the heel post to bring the shoe approximately into the plane of the heel seat wipers 3 and thereafter, while the pawl 214 holds the shoe elevated, to jack the shoe back into the heel band by means of the hand wheel 148 andthen to jack up the toe of the shoe by means of the treadle 17 6. This is the most advantageous sequence of steps now known to me because it provides for jacking the shoe into the heel band at the correct elevation and avoids displacing the last upwardly in the shoe after the shoe has been embraced by the heel band.

As explained in said prior patents, the latch 144 that locks the heel carriage is automatically released in response to the unjacking depression of the foot treadle 176, allowing retracting spring 145 to slide the heel carriage rearwardly, and in the 0011- I tinued depression of treadle 176 the operator depresses a treadle 165 for effecting release of the locking pawl 150 from hand wheel 148. The mechanism for releasing the heel carriage is shown in detail in Fig. 3 and comprises a rock shaft 81 upon which the latch 144 is mounted, and an arm 83 carried by the rock shaft 81 and extending over a cross bar 84 supported upon a vertically move I able rod 87 operated by a cam 89 upon the cam shaft 9. In the operation of this mechanism, that movement of the treadle 176 whereby the toe post is released and permitted to return to its lowered position serves to operate the cam 89 in such a manner as to raise the arm 83 and thereby elevate the latch 144 for releasing the heel carriage, thus permitting the heel carriage to be moved rearwardly through the action of its spring 145.

In accordance with the illustrative emnausea bodiment of this invention the heel lasting carriage has a laterally projecting stud 25 arranged to engage, during the rearward movement of the heel lasting carriage, with the upright arm 26 of a rockshaft 27 having a horizontal arm from which is suspended a lifting plate 28. The lifting plate underlies the head of a. lifting rod 30 operatively connected with the pawl 214 so that when the heel carriage moves rearwardly, or toward the right. in Fig. l, the shaft 27 will be rocked, lifting plate 2.8 and the pawllifting rod 30. This arrangement provides that the elevating rod 210 will be released and allow the heel post and the shoe to drop away from the heel wipers automatically and concurrently with the other unjacking operations. The. arm 26 has a depressible end member 40 provided with a rearwardly and downwardly inclined face to engage the stud 25 and cause the stud to force the member out of its way as the heel'lasting carriage is moved toward the left to its workinglposition.

aving explained the nature of this invention and described an illustrative embodiment thereof, I claim as new and desire to secure by Letters Patent of the United States*.
